CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 418,487, dated December31, 1889. Application filed June 1'7, 1889. serial No. 314,619. (Nomodel.)

To aZZ whom it may concern:

Be it known that I, EDWARD BEST, a citizen of the Dominion of Canada,residing at Carleton Place, in the county of Lanark and Province ofOntario, Canada, have invented certain new and useful Improvements inCar- Axle Boxes; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

My invention, which will be hereinafter fully set forth and claimed,relates to caraxle boxes; and the object is to provide an oiler forrailway-car axles that will work automatically, giving a continuous andsuflicient supply of oil to the bearing so long as the axle is moving,that will also be simple in its parts, admitting of a strongconstruction, and that will not be likely to get out of working order.

It consists, essentially, in the usual outer case or box, a removabletop bushing and key, and an inclosed oil-vessel, of which the top wallis depressed to form a circular recess, bored or otherwise fitted so asto lie closely against the under side of the axlebearing, against whichit is held by strong springs, and rising around the sides of the axle ashigh, or nearly as high, as the center of the axle, at which point theoil-vessel is supplied with oil. The oil-.vessel is provided withgutters for catching the surplus oil, with creases for giving anefficient distribution of the oil, and with an opening through which theoil rises against the axle, and this keeps it constantly and perfectlylubricated.

In the accompanying drawings, which illustrate my invention, Figure 1 isa longitudinal section of my improved axle-box with a portion of theaxle in place. Fig. 2 is a transverse section on line 00 00. Fig. 3 is aplan view of the oil-vessel.

The outer case A is simply the ordinary plain-sided box that is commonlyused for this purpose. An opening is made in its inner side for theentry and vertical play of the axle. The outer side of the box isprovided with the hinged door B, through which access is had to theinside for refilling the oil-vessel or other purposes. The top bushing 9is set in place over the axle and between the shoulders of its bearing,and over this bushing is placed the fillet D, which is kept fromsideward motion by the ribs E, which are formed on the inner surfaces ofthe case A. The oil-vessel F is preferably made nearly the whole lengthof the bearing, and has its oil-escape opening G made to extend as muchas possible along its length, by which means the entire length of theaxle-bearing is equally supplied with oil. When the 011- vessel isfilled, the oil extends well up on each side of the axle, so that itsgravity will insure an outward pressure through the opening G. Theoil-vessel is held up against the axle by the springs H. Oil-creases Jare made in the bearing-surface of the oil-vessel, by which means thesupply of oil is more evenly distributed around the axle. It Wlll beseen on reference to Fig. 1 that the channels or oil-creases J extendboth longitudinally and transversely of the oil-vessel. This insures thecomplete distribution of the 011 to the bearing-surfaces. Theoil-gutters K, which are made in the highest parts of the vessel, catchany superfluous oil that might drip from the top bushing, and being openat the bottom allow the oil to pass from them into the lower part of thevessel.

What I claim as new, and desire to secure by Letters Patent, is

1. The oil-vessel for an axle-lubricator, provided with the concave tophaving the opening therethrough for the emission of the lubricant, thesaid box provided with the downwardly-sloping side edges projectingbeyond the axle, and with openings therethrough for the entrance of thelubricant, substantially as described.

2. The oil-vessel for an axle-lubricator, having the concave top andopening for the escape of the oil, and the projecting side edges, saidedges formed with the downwardly-inclined lips and with theoil-admission openm s.
